[0035] Reference Figures 1 to 6 The present invention provides a hair dyeing device 100 .

[0036] In an embodiment of the present invention, the hair dyeing device 100 includes a shell 10, wherein the shell 10 is formed with at least one liquid storage chamber 12a, a liquid outlet 12b and a mixing channel 10a, wherein the liquid outlet 12b connects the liquid storage chamber 12a and the mixing channel 10a; a mixing element 60, wherein the mixing element 60 is arranged in the mixing channel 10a; a liquid outlet head 20, wherein the liquid outlet head 20 is connected to the shell 10 and is provided with a liquid outlet 20a connected to the mixing channel 10a; and an extrusion component, wherein the extrusion component includes an extrusion component 31, wherein the extrusion component 31 is connected to the shell 10 and can reciprocate in the liquid storage chamber 12a, wherein the extrusion component 31 is used to drive the hair dye into the mixing channel 10a and be discharged from the liquid outlet 20a.

[0037] Specifically, the housing 10 of the present application can be formed of metal or plastic material, and the housing 10 includes a main housing 11, a liquid storage cylinder 12, and a dust cover 14, wherein the main housing 11 is a shell-shaped cavity structure, forming an installation cavity 11a for installing various components of the hair dyeing device 100, and the main housing 11 is extended in a cylindrical shape as a whole, and its two opposite ends are divided into a hair dyeing end and a holding end, and the liquid storage cylinder 12 is arranged at the holding end and is detachably connected to the main housing 11, and the liquid storage cylinder 12 and the main housing 11 are enclosed to form a liquid storage cavity 12a for holding hair dye. The dust cover 14 is arranged at the hair dyeing end, and is detachably connected to the main housing 11 through a connection structure such as a buckle, a magnet, etc. The dust cover 14 and the main housing 11 are enclosed to form a sealed cavity, and a comb head 40 is arranged in the sealed cavity. By setting the dust cover 14, the comb head 40 can be protected when it is not in use. The mixing channel 10a is partially disposed in the main housing 11 and partially disposed in the liquid storage cylinder 12. The liquid outlet 12b is disposed on the side of the liquid storage cylinder 12 away from the main housing 11, that is, at the bottom of the liquid storage cylinder 12. In the present invention, by disposing the liquid outlet 12b at this position, the length of the mixing channel 10a can be further extended, so that the time for the hair dye to flow in the mixing channel 10a is as long as possible, that is, the mixing time is extended, so that the mixing effect of the hair dye is further improved. Of course, the liquid outlet 12b can also be disposed in the middle or top of the liquid storage chamber 12a, and its position can be set according to actual needs, and is not specifically limited here.

[0038] The liquid outlet head 20 can also be formed of metal or plastic material, and is formed with a liquid outlet channel and a plurality of liquid outlets 20a connected to the liquid outlet channel. The end of the liquid outlet head 20 can be partially inserted into the mixing channel 10a, so that the liquid outlet channel and the mixing channel 10a are connected, and the hair dye is discharged outward from the plurality of liquid outlets 20a. In the present application, the liquid outlet head 20 is inserted into the end of the mixing channel 10a, and its connection method is simple, which is convenient for disassembly, maintenance and cleaning.

[0039] In the present invention, the hair dyeing device 100 also includes a combing head 40, which is integrally formed of a plastic material, and a first magnetic part is arranged at the bottom thereof, and a second magnetic part is arranged correspondingly on the main housing 11, and one of the first magnetic part and the second magnetic part is a magnet, and the other of the two can be a magnet or a magnetic metal, such as iron, steel, etc., that is, the combing head 40 and the main housing 11 are detachably connected through the first magnetic part and the second magnetic part. The combing head 40 is waist-shaped as a whole, and the middle part is a liquid outlet area 40a, and the liquid outlet area 40a is provided with a plurality of liquid outlet gaps, and the plurality of liquid outlet gaps correspond to the plurality of liquid outlet ports 20a. The hair dye is applied to the user's hair through the plurality of liquid outlet gaps, and the combing area 40b is provided outside the liquid outlet area 40a, and the combing area 40b is convexly provided with a plurality of comb teeth. After the hair dye is applied to the hair, the comb teeth arranged around the outside of the liquid outlet area 40a can further evenly apply the hair dye, thereby improving the hair dyeing effect of the hair dyeing device 100.

[0040] In the present invention, one or more hair dyes are stored in the liquid storage chamber 12a. Under the action of external force, the extruder 31 moves in the liquid storage chamber 12a. Under the action of atmospheric pressure, the hair dye is squeezed into the mixing channel 10a. After entering the mixing channel 10a, the hair dye is mixed or further refined by the mixing element 60 disposed in the mixing channel 10a, and the mixed hair dye is discharged to the outside through the liquid outlet 20a. In the present invention, since the discharged hair dye passes through the mixing channel 10a and is mixed and stirred by the mixing element 60 disposed therein, the uneven mixing of the hair dye can be avoided, and the hair dyeing device 100 has a better effect of applying the hair dye.

[0041] Please refer to the Figure 2 and Figure 7 It should be noted that, generally speaking, more than two hair dyes are needed when dyeing hair. When there is only one liquid storage chamber 12a, in order to ensure a better mixing effect of the hair dyes, a stirring tool may be used to pre-stir the two hair dyes after adding them to ensure that the two hair dyes can be fully in contact. The simple structure of one liquid storage chamber 12a facilitates production and manufacturing. In other embodiments, two or three liquid storage chambers 12a may be provided, and one liquid storage chamber 12a is connected to the mixing channel 10a through a liquid port 12b, so that the addition and cleaning of the hair dye are more convenient. At the same time, one hair dye is stored in one liquid storage chamber 12a, which can also facilitate the user to control the mixed dosage. The number of liquid storage chambers 12a is not specifically limited.

[0042] Further, in the present invention, the liquid storage cylinder 12 is provided with connecting buckles 121 on opposite sides, and the main housing 11 is provided with connecting buckles 11b that are also adapted to the connecting buckles 121. The connecting buckles 121 can be buckled into the connecting buckles 11b to connect the liquid storage cylinder 12 and the main housing 11. By providing the connecting buckles 121 and the connecting buckles 11b, the liquid storage cylinder 12 and the main housing 11 are connected, which is not only simple in structure, but also convenient for users to disassemble and assemble the liquid storage cavity 12a, add hair dye to the liquid storage cavity 12a, or clean the liquid storage cavity 12a. Of course, the liquid storage cylinder 12 and the main housing 11 can also be connected by threads, screws or magnets, which will not be described in detail here.

[0043] Please see again Figures 4 to 6 In one embodiment of the present invention, the mixing element 60 includes a threaded mixing rod 61, which is disposed in the mixing channel 10a and is detachably connected to the liquid storage cylinder 12. Specifically, the mixing element 60 also includes an end cap 62. A plug-in slot 11c connected to the mixing channel 10a is provided on the side of the liquid storage chamber 12a away from the main housing 11, that is, the bottom wall of the plug-in slot 11c is connected to the mixing channel 10a, and the slot opening of the plug-in slot 11c faces the bottom of the liquid storage cylinder 12, and its diameter is the same as that of the end cap 62. A limiting protrusion (not shown) is formed at the end of the threaded mixing rod 61. When the threaded mixing rod 61 extends into the mixing channel 10a from the plug-in slot 11c, the limiting protrusion fits the opening of the mixing channel 10a, and the end cap 62 is clamped in the plug-in slot 11c and abuts against the limiting protrusion, thereby fixing the threaded mixing rod 61 in the mixing channel 10a. In the present application, by setting a threaded mixing rod 61 in the mixing channel 10a, on the one hand, the flow distance of the hair dye in the mixing channel 10a can be further extended, thereby improving the mixing effect of the hair dye; on the other hand, the spiral channel formed by the threaded mixing rod 61 can compress the hair dye, thereby increasing the speed of the flow and mixing of the hair dye, thereby improving the mixing effect of the hair dye. In addition, the threaded mixing rod 61 of the present application is fixed to the mixing channel 10a by the end cover 62, and its structure is simple, which is convenient for customers to clean the threaded mixing rod 61. Of course, the threaded mixing rod 61 can also be directly connected to the end cover 62 by gluing or hot melting, or connected to the end cover by screws or threaded connections, etc., which are not specifically limited here.

[0044] Furthermore, in the present invention, the housing 10 is provided with a sealing ring 13, which is sleeved on the outer side of the end cover 62. When the end cover 62 is clamped in the insertion groove 11c, the end cover 62 elastically abuts against the end cover 62 and the groove side wall of the insertion groove 11c. The sealing ring 13 can make the connection between the end cover 62 and the liquid storage cylinder 12 more firmly, and can also prevent the hair dye in the mixing channel 10a from flowing out of the insertion groove 11c.

[0045] In another embodiment of the present invention, the mixing element 60 may also be other structures. For example, the mixing element 60 includes a mounting rod, on the surface of which a plurality of blocking protrusions are formed. The plurality of blocking protrusions are arranged at intervals along the extension direction and circumferential direction of the mounting rod. By providing a plurality of blocking protrusions, the hair dye can be further mixed and stirred.

[0046] The threaded mixing rod 61 and the liquid storage cylinder 12 are connected in a detachable manner to facilitate cleaning. Of course, the thread on the threaded mixing rod 61 can also be provided on the side wall of the mixing channel 10a in an integrated manner; or a plurality of protrusions can be provided on the side wall of the mixing channel 10a to improve the mixing effect of the hair dye, thereby reducing the number of parts of the hair dyeing device 100, improving the assembly efficiency of the hair dyeing device 100, and improving the production capacity.

[0047] Please see again Figures 2 to 4 In this embodiment, the extrusion assembly also includes a driving member and at least one transmission member 33, wherein the driving member is installed in the installation cavity 11a of the main shell 11, the extrusion rod is arranged in the liquid storage cavity 12a, and the transmission member 33 connects the driving member and the extrusion member 31.

[0048] Specifically, the transmission member 33 includes a transmission sleeve 331 and a transmission screw 332, and the driving member includes a driving motor 321, which can be a servo motor or a stepping motor. The driving motor 321 is fixed in the installation cavity 11a, and its output shaft sleeve is provided with an output gear 322. One end of the transmission screw 332 is sleeved with a driven gear 324, and the other end extends toward the liquid storage cavity 12a. The driven gear 324 is meshed with the output gear 322. The interior of the transmission sleeve 331 is provided with a thread matching the transmission screw 332. The transmission sleeve 331 is sleeved on the outside of the transmission screw 332 and extends toward the liquid storage cavity 12a. The middle part of the transmission sleeve 331 is slidably connected to the main housing 11, and its end is fixedly connected to the extrusion member 31, and the extrusion member 31 slides back and forth in the liquid storage cavity 12a.

[0049] In actual application, when the hair dye needs to be injected into the mixing channel 10a, the driving motor 321 rotates clockwise or counterclockwise, and drives the transmission screw 332 to rotate clockwise or counterclockwise through the output gear 322 and the driven gear 324, thereby driving the transmission sleeve 331 connected thereto to rise and fall, and when the extrusion member 31 moves toward the bottom wall of the liquid storage chamber 12a, the hair dye is squeezed into the mixing channel 10a by atmospheric pressure, and when the extrusion member 31 moves toward the bottom wall away from the liquid storage chamber 12a, part of the hair dye is extracted from the mixing channel 10a. In the present application, the structure of the driving member and the transmission member 33 is relatively simple, and through the cooperation of the transmission sleeve 331 and the transmission screw 332, the movement speed of the extrusion member 31 can be well controlled, and thus the extrusion amount of the hair dye can be well controlled.

[0050] In another embodiment of the present application, the transmission member 33 includes a transmission gear 323 and a transmission rack, wherein the transmission gear 323 is sleeved on the output shaft of the driving motor 321, the transmission rack is slidably connected in the installation cavity 11a, and is connected to the extrusion member 31, and the transmission gear 323 is meshed with the transmission rack. When the driving motor 321 rotates, the extrusion member 31 is driven by the transmission rack to reciprocate in the liquid storage cavity 12a.

[0051] It is understandable that the function of the driving member and the transmission member 33 is to drive the extrusion member 31 to reciprocate in the liquid storage chamber 12a, so its structure can be set according to actual needs. For example, the driving member includes a driving cylinder, and the transmission connection is a transmission rod, one end of the transmission rod is connected to the telescopic rod of the driving cylinder, and the other end is connected to the extrusion member 31, that is, the driving cylinder drives the extrusion member 31 to reciprocate in the liquid storage chamber 12a.

[0052] For example, in another embodiment, a driving chamber is formed in the installation cavity 11a, and the main shell 11 is provided with two air ports connected to the driving chamber. Part of the extrusion member 31 is located in the driving chamber, and the two air ports are respectively connected to the air pump. That is, the extrusion member 31 is driven to reciprocate in the liquid storage chamber 12a by taking air in or out of the driving chamber.

[0053] In the present application, the extrusion member 31 includes an elastic washer 312 of an extrusion seat 311, wherein the extrusion seat 311 is integrally formed of a plastic material, and a slot matching the end of the transmission sleeve 331 is provided on its upper surface, and the elastic washer 312 is made of a silicon cavity or rubber, and is sleeved on the outer side of the extrusion seat 311. When the extrusion seat 311 is placed in the liquid storage cavity 12a, the elastic washer 312 elastically abuts against the side wall of the liquid storage cavity 12a. By providing the elastic washer 312 elastically abutting against the side wall of the liquid storage cavity 12a, it is possible to effectively prevent the extrusion seat 311 from flowing out of the gap between the two when the hair dye is squeezed into the mixing channel 10a.

[0054] Furthermore, in order to ensure the balance of the movement of the extrusion seat 311 in the liquid storage chamber 12a, in one embodiment of the present invention, the extrusion assembly includes two transmission members 33, the driving member includes an output gear 322, two transmission gears 323 and two driven gears 324, the output gear 322 is sleeved on the output shaft of the driving motor 321, a driven gear 324 is sleeved on the end of a transmission screw 332, the two transmission gears 323 are respectively meshed with a driven gear 324 and the output gear 322, and the two transmission members 33 are respectively connected to the opposite sides of the extrusion seat 311. In the present invention, by providing two transmission members 33, the stability of the movement of the extrusion seat 311 in the liquid storage chamber 12a can be ensured to a large extent, and the deflection thereof can be avoided. At the same time, through the mutual cooperation between the output gear 322, the two transmission gears 323 and the two driven gears 324, one driving motor 321 can drive the two transmission members 33 to move, so that the structure of the extrusion assembly is relatively simple, and it is easy to produce and assemble.

[0055] In the present invention, a control assembly 50 is further provided in the installation cavity 11a, and the control assembly 50 includes a control board 51 and a control switch 52, wherein the control board 51 is composed of a printed circuit board (PCB) and a plurality of electrical components welded on its surface, the control switch 52 is welded on its surface, the drive motor 321 is connected to the control board 51 through a terminal connection line, and the control switch 52 can be used to control the opening, closing or use state of the hair dyeing device 100. By providing the control board 51 and the control switch 52, it is convenient for the user to control the hair dyeing device 100.

[0056] In this embodiment, the control assembly 50 further includes a Hall switch (not shown), wherein the Hall switch is installed in the installation cavity 11a and is communicatively connected with the control board 51 through a terminal connection line, and the Hall switch is used to limit the movement stroke of the extrusion member 31. Specifically, when the extrusion member 31 moves to a preset position in the liquid storage cavity 12a, the Hall switch is triggered accordingly, and at this time, an electrical signal is transmitted to one side of the control board 51, and the control board 51 controls the driving member to work accordingly, thereby ensuring the stable and smooth operation of the extrusion assembly.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
